I would suspect MAP. Theres no loom after the throttlebody, and it looks like the map will be on the black plastic intake near the TB.

If you had to disconnect any wiring from the air hose then it has a MAF.

They are quite different, one is a small plastic pressure sensor which measures relative pressure - the other is a hot wire mesh which calculates oxygen mass from a temperature change which is considerably bigger.

The best bet would be to pull the engine code from the chassis, unless its a donor - but in any case there should be a stamp on the block somewhere with a 3 letter code. If not the stickers are in the usual places on the car - door pillar, boot, bonnet. Or if you can translate your Chassis codes on the V5 you will also see the engine code in there.

Map sensor at the end of the manifold where the dipstick tube heads down, no maf on that engine as far as I'm aware, if memory of my 1.4 16v serves me right.

Engine codes AEH, AKL & APF all have MAF sensors (no MAP).
Engine codes ATN, AUS & AZD all have MAP sensors (no MAF), but if your engine isn't one of those, post your engine code and I'm sure someone will be able to tell you for sure what your engine has.
The engine code should be on the white label on the timing cover.

very comprehensive and just the right info to find the car and engine details
i did think it might have been the little sensor near the TB but being so new to this side of the engine functions needed to get some help
thanks very much
cheers
